Potential artificial radio signal from K2-155 system
Overview
Astronomers using China’s Five-hundred-meter Aperture Spherical Telescope (FAST) have identified an unusual radio signal originating from the direction of the K2-155 red dwarf star system, located approximately 238 light-years from Earth.
Initial observations reported a narrow-band signal at 1140.604MHz that exhibited frequency shifts due to the Doppler effect. Researchers utilized a multibeam coincidence matching method to suggest the signal was not local radio noise, as it was detected in only one beam.
Subsequent investigations focused on the signal, designated NBS 260108, identified at a frequency of approximately 1,148.4167 MHz. The K2-155 system contains three known super-Earths, including K2-155 d, which orbits near the habitable zone. While the gradual frequency shift is a characteristic that can be associated with technological transmissions, scientists emphasize that this does not constitute conclusive evidence of an extraterrestrial origin and continues to be investigated to rule out human-made interference.
